Taylor Swift Vienna concerts cancelled over terror plot

Austrian security officials say a 19-year-old arrested on Wednesday was planning to kill "a large crowd of people" in a suicide attack at a Taylor Swift concert in Vienna.

Officials say the teen - who had previously pledged allegiance to the Islamic State group (IS) - confessed that he "intended to carry out an attack using explosives and knives".

Swift's three sold-out shows at the Ernst Happel Stadium have been cancelled. More than 195,000 people had been expected to attend.

Local media have also reported that the 19-year-old, the main suspect out of three, had stolen chemicals from his former workplace.
